#306: instance branding — logo and favicon, cropped in the browser
An instance had no way to look like itself: the top bar said "Dorfteich"
whatever the operator called their instance, `instance.name` was never
rendered in the running app at all, and there was no favicon anywhere —
`index.html` had no `<link rel="icon">` and `public/` held only fonts and
theme-init.js.

Where the line is drawn, and why:

- **The api never decodes an image.** Cropping, scaling and the conversion
  to PNG happen on a canvas in the browser; the api checks the PNG
  signature, reads the IHDR dimensions at their fixed offsets and enforces
  the caps. An image library would put a decoder in front of
  attacker-supplied bytes AND would have to be carried through the
  `--network none` offline build. Reading two big-endian integers is not
  decoding.
- **SVG is refused**, with its own error message rather than a generic
  "not a PNG": it can carry script, and serving it from our own origin
  would be a cross-site-scripting vector. An operator who tried one should
  learn that it is deliberate.
- **The crop is driven by number inputs, not by dragging.** A drag-only
  cropper excludes keyboard and switch users outright; a number input is
  arrow-key operable and screen-reader readable without any custom aria.
  The resulting pixel size is stated in text, not only drawn as a frame.
- **The variant is chosen by CSS, not JavaScript.** `theme-init.js` has
  already resolved `data-theme` before first paint, so the correct logo is
  the one painted rather than the one that appears after a flash. Without a
  dark variant the LIGHT logo carries both themes — the operator's own
  asset shown unchanged beats one they did not choose (the rule #307
  extends to ponds). The settings screen warns; it never blocks.
- **The favicon link is static, its resource dynamic.** index.html stays a
  static file and the api answers with the uploaded icon or a shipped
  default — that route must never 404, or the browser keeps its generic
  icon for good. The default is generated by a script from Node's own zlib
  (`gen-default-favicon.mjs`), for the same offline-build reason.
- Both favicon sizes are uploaded together: one source, one crop, so the
  tab icon and the home-screen icon can never disagree.
- Branding is served WITHOUT a session, because the login screen carries it
  and the browser fetches the favicon before anyone signs in. The admin
  screen says so — an operator may not expect their logo to be public.
- The metadata is not writable through the settings endpoint: it describes
  bytes on disk, and hand-writing it would claim an asset that is not
  there.

`./data/branding` follows the three-step rule #303 paid for: env default +
`data-dirs.ts` entry, compose volume (repo AND the stages on ONE), and the
`mkdir`/`chown` line in the api Dockerfile. `data-dirs.test.ts` is new and
closes the hole that made #303's variant invisible: the nightly archive
skips a missing directory WORDLESSLY, so the fence now demands that every
`*_DIR` the backup env declares actually travels in the archive. Verified
against the real defect — removing the line fails it by name.

Audit catalogue v1.7 (`branding.changed`), carrying `scope` from the start
so #307 is the same event with a different scope, not a second id.

Verified: api suite 103 files green (a lone `public-api` ECONNRESET under
local parallel load, green in isolation — the documented local flake);
branding suite 12 tests against a real directory; crop arithmetic unit
tests; a11y pack 11/11 in both schemes; /admin measured at 320px with the
new section (overflow 0); and the whole flow walked in the browser: upload
→ crop 780×180 → stored as 512×118 → logo in the sidebar linking home with
the instance name as its accessible name → topbar wordmark following
`instance.name` → light logo still shown under `data-theme="dark"`.

Dorfteich

Dorfteich is an open-source wiki system built around ponds (German: Teiche) — self-contained wiki spaces that people and teams organize freely with hierarchical labels, directories, and Obsidian-style page relations. Pages are edited in a collaborative WYSIWYG editor with live cursors and offline support.

Key features

  • Real-time collaboration — multiple people edit the same page simultaneously; everyone sees the other participants' cursors and input live. Offline edits merge conflict-free on reconnect (CRDT-based).
  • Ponds — isolated wiki spaces with their own members, permissions, fonts, and page organization. Every registered person gets a personal pond.
  • Flexible organization — hierarchical labels, free page ordering, [[wikilinks]] with backlinks. A classic page tree is possible but never enforced.
  • Fine-grained permissions — roles (Site Admin, Pond Admin, Editor, Reader, Public) can be granted per pond, per label, or per page; the most specific setting wins.
  • Import & export — Markdown as the primary exchange format, plus best-effort structural import from Word/OpenOffice and export to Word/OpenOffice/PDF.
  • Plugins — sandboxed extensions (custom blocks, styles, page tools) installable at runtime without redeploying the instance.
  • Self-hosting first — a single docker compose up plus a guided first-run setup wizard yields a working instance. Start here: docs/self-hosting/README.md.

Development

Requirements: Node.js ≥ 22 and pnpm (npm install -g pnpm).

pnpm install        # install all workspace dependencies
pnpm lint           # ESLint + Prettier check across the repo
pnpm typecheck      # TypeScript --noEmit in every package
pnpm test           # Vitest in every package
pnpm build          # build every package (dependency order)

The workspace packages live under apps/ (web, api, collab) and packages/ (shared). Shared logic goes into packages/shared and is imported as @dorfteich/shared — never copy code between apps.

Status

Feature-complete for a 1.0: collaboration, permissions, import/export, plugins, public REST API + MCP, backups with off-host copies and in-app restore — all shipped and release-gated. Work is tracked as issues in this repository.
